This article presents the results of research on laboratory cultivation of Cynara scolymus L, a PGPR-based bioproduct - elicitor and Zamin-M. Experiments have shown that plant seeds inoculated with Elicitor biological products continue to grow under sterile conditions in 1.6% agar feed compared to other options.

A well-known citrus plant, very common in the culture of Central Asian countries. Lemons grown in greenhouses, hotbeds. It found wild in Southeast Asia. It is eaten everywhere. The plant, due to its taste, flavoring properties, is widely used in the confectionery, wine and vodka industries. Lemons used in cosmetology. The plant has been used in medical practice since ancient times. In article, the review of literature on medicinal and preventive properties of fruits of a lemon is provided in ancient, modern traditional and scientific medicine. Citrus L, as an evergreen subtropical plant, successfully used in Uzbekistan under protected ground conditions as an industrial crop, and indoors as an ornamental crop, but the success of this crop depends on the variety and cultivation technology.

This article reveals the results of the study on different planting schemes for Margilan 330, Uchkun and Tillarang varieties of hot chili peppers in unheated greenhouse conditions. According to the results of the study, the number of fruits was higher in 70x20 cm reduced variants of planting scheme, while in the variants planted in 70x50 cm scheme, the fruit weight increased even though the number of fruits was less.

Dangerous pest is widespread in Uzbekistan. The most dangerous of these are coccidia. They damage many plants. Damages pomegranate, date, unabi, apple, pear, plum, quince, peach, almond, hawthorn, pine, poplar and other orchards and ornamental trees.

In Uzbekistan, comstock worms reproduce three times a year, and partly for the fourth time. But with the fall of the cold, the fourth generation perishes.

In pomegranate and palm crops, different levels of infestation were observed in different varieties by comstock worms. In pomegranate, 53.8% of Ok dona, 49.5% of Kizil anor, 39.1% of Kozoki anor and 22.8% of Achchik dona were damaged. 38.3% of Zenju-maru, 25.9% Tamopan and 20.1% Xiakume dates were damaged.

In order to identify the main pests of seed orchards, as a result of observations on apple, beech and pear orchards on farms in Tashkent region, 3 genera Lepidosaphes, Diaspidiotus and Parlatoria belonging to the family Diaspididae were recorded in orchards.

They were found to be distributed in 3 species Lepidosaphes ulmi (Linnaeus, 1758), Diaspidiotus perniciosus (Comstock, 1881) and Parlatoria oleae (Colvée, 1880) from the family Diaspididae, and 2 were recorded as dominant species.

In order to create a species composition and GIS map of the Diaspididae family in seed orchards, 12 coordinates of pests in apple, quince and pear orchards were determined and a GIS map was constructed.

Plate-molded composite designs are commonly carried out in an assortment of utilizations connected with the aviation or auto industry. Exposed to genuinely natural conditions, those designs might be troubled by sway loads. Low-speed impacts specifically are a high security issue since they can cause scarcely apparent or imperceptible harms inside the design. The caused surrenders change from scores and breaks to delaminations on a deeper level. Their normal outcome is a huge decrease of pressure and exhaustion strength. To decide the respectability of composite designs, various standards, for the most part ultrasonic testing, can be utilized. Since these techniques are normally tedious, a quicker and all the more effortlessly applied essential test strategy may offer benefits. Such a test technique can be acquired by examining the vibrational conduct of composite designs. Utilizing the vibrational examination approach, the reaction frequencies are thought of, yet in addition other modular properties, particularly the modular damping.
